Unstable t810 with naza.

[alehed]

Hi.
I have a problem. My tarot t810 with a naza m on it is a bit scary when i take off.
when i´m taking off at first i put the stick gently above center and it takes of but when i lower the stick back to stop it from going upp it´s like one of the motors stop and it just drops and as fast as i give it a bit more throttle it´s stable again.
when hovering it´s stable.
Don´t know what´s wrong so please help.

Thanks Jonas

I'm not familiar with the Naza, but check your esc calibration. My pixhawk will do something similar if I don't calibrate the escs. Does it take off smoothly or does it wobble around as it rises?
